The patent shows how a monitoring system could be cleverly built into Apple earphones, and used to track activity such as speed and distance traveled during exercise. The device would also be able to sense other biometric data relating to metrics body temperature, perspiration rate, and heart rate.

The iOS gaming experience is about to get a whole lot more interactive, thanks to Israeli startup Umoove.

With its new app Umoove Experience, downloadable free of charge from the App Store, gamers can have a go at piloting a 3D avatar flying over a village — enabling them to control navigation entirely by face and head gestures.

According to Topeka Capital Markets analyst Brian White earlier this year, Apple’s busy working on an “iRing" finger ring we’ll use to control our Apple devices with. The suggestion was so preposterous that even the usually poker-faced Tim Cook cracked a joke about it.

The reality is that much of the “digital hub” functionality that an iRing would have brought will likely be carried out by the iWatch when it finally surfaces. For those who really wanted this rumor to be true, however, never fear: several companies have created their own third-party iRings to bring this rumor to life.

While those predictions may not have come to fruition just yet, music technology company IK Multimedia is launching an iRing of its own that will allow people to perform specific tasks on their iOS devices using gestures.

Multi-touch? Pah, that’s so last year. Gestures are where it’s at. Only yesterday, we reported on a prototype wrist-mounted motion detector; today, we’re trying out Flutter, a free OS X app that we first mentioned back in March when it was still a demo.

Now it’s available in the Mac App Store. It claims to put gesture controls at your, um, fingertips, using your Mac’s built-in webcam.
